File Size - iMovie

I have a movie made in imovie. I have imported the footage in one burst - 45min clip- and edited it down, emptied the trash and saved project.

But all the bits and bobs that end up on the cutting room floor are still saved in the movie, presumably so i can always revert the clip to original! How do i save so that all the superfluous stuff is a gone!?

Export the movie as it is to a DV stream. Re-import as new project, delete old project.

Unfortunately you'll loose a bit of flexibility though...

thanks a lot aptmunich. ok, so i have to export it. what are the best settings to export? is it dv stream or quicktime. i thought quicktime was better quality... wrong? do you know the exact best settings? thank you soo much for your help.

DV Stream is the pure uncompressed video format used by your camcorder, Quicktime is a flexible video format that can use very high quality codecs that look great, but ultimately it is always compressed in some form AFAIK.

is that dv? dvcpro? or dvcpro50? if dv, what rate? 48.000, 44.000, 32.000?
i did a small test and exported a clip as a dv stream and the same as quicktime. the quicktime was about 100mb and the dv about 70mb. so the dv seamed to compress more though. what did i do wrong?
thanks for your patience.
